Introducing the TN3270 Emulation Program
Overview
Table 1-1 3270 Display Models
You can display screen models other than Model 2 only if your HP-UX
computer and your terminal's screen hardware can support them.
However, you can activate sessions that use any screen model and use
HLLAPI application programs to access them, even if you cannot access
these sessions directly. Refer to the HP-UX SNAplus2 3270 & TN3270
HLLAPI Programmers Guide for more information.
File Transfer
The TN3270 emulation program supports file transfer using the IBM
host file transfer program IND$FILE (or APVUFILE for double-byte host
languages), enabling you to transfer files between your local computer
and MVS/TSO, VM/CMS, and CICS host systems. You can transfer
multiple files, with multiple hosts, at the same time. Each file transfer
uses a separate active 3270 display session.
You can perform the following file transfer operations:
• Transfer both text and binary files, and sequential and partitioned
data sets with fixed- or variable-length records. As a file is
transferred, it can be translated from ASCII to EBCDIC or vice versa.
• Choose to insert or strip away carriage-return and line-feed
characters.
• Send multiple HP-UX files to a host.
• Append a transferred file to an existing file on a host or on the HP-UX
computer.
• Print the contents of any HP-UX file on a host-connected printer by
transferring the HP-UX file to a host file or data set and then printing
that file on the host printer.
